Jeff Burton's announcement Wednesday that he won't drive the No. 31 Chevrolet again in 2014 in NASCAR's Sprint Cup Series is the latest in a flurry of NASCAR driver-team changes for this season and next year.

Haven't kept up with all of them? Here's a scorecard to help you stay current:

Ryan Newman, currently one of three Stewart-Haas drivers with Tony Stewart and Danica Patrick, is looking for a ride for next year after not being re-signed.

Stewart is out for the rest of the season with a broken right leg.

Mark Martin, who had driven the No. 55 Toyota part-time for Michael Waltrip Racing, will replace Stewart in his No. 14 Chevrolet in all but one of the remaining races this year. The exception is Oct. 20 at Talladega, Ala., where Austin Dillon will drive.

Brian Vickers, who had been another co-driver on the No. 55, takes over that car for this year's remaining races except Talladega -- where Waltrip himself will drive -- and stays in the car full-time next year.

Juan Pablo Montoya will not be back to drive the No. 42 Chevy next year for the team Earnhardt Ganassi Racing with Felix Sabates. Montoya will be replaced by 21-year-old Kyle Larson.

A.J. Allmendinger will drive the No. 47 car full-time next year for JTG Daugherty Racing. Bobby Labonte, currently sidelined after a cycling accident, had driven the car for most of this year.
